Voltage regulator: A device which maintains the correct voltage level in a vehicle's electrical system by preventing the circuit voltage from exceeding a predetermined safe value. When the battery needs charging the regulator cuts resistance out of the generator field circuit, thus increasing the flow of current in that circuit, with the further result that output is increased. When the battery becomes fully charged, the resistance is cut back into the field circuit so that the charging rate is decreased. As the engine speed increases, the alternator increases and generates more voltage. Unchecked, the alternator might put out so much voltage that bulbs and other electrical components might burn out. To a certain extent, the battery acts as a voltage regulator, but it too can be damaged by an electrical system. which does not have an operating voltage regulator.

Voltmeter: An instrument used to measure the voltage in a given circuit, in volts.

Volume: The measurement, in cubic inches, cubic feet, etc., of the amount of space within a certain object or area. Also see displacement.

Volumetric efficiency: A comparison between the actual volume of fuel mixture drawn in on the intake stroke and what would be drawn in if the cylinder were to be completely filled. Also see breathing capacity.

Voluntary Export Restraint: (VER) In relation to Japanese manufacturers exporting to Canada (no longer in effect).

Voluntary Restraint Agreement: In relation to Japanese manufacturers exporting to the United States (no longer in effect).

Volute: A spiral-shaped case in which an impeller forces liquid in the direction it should go. Often used in pumps. Also see impeller.

Vortex flow: The whirling motion of the oil in a torque converter as it moves around and around from the pump, through the turbine, through the stator and back into the pump and so on.

Volvo: The 1961-67 P.1800S, 2-door Coupe models are milestone cars.

VRA: Acronym for "Voluntary restraint agreement".

VTEC Valve system: !!!.

V type engine: See V-type engine.

V-type engine: An engine in which the cylinders occur in two rows set at an angle to each other with the crankshaft running through the point of the V. The single crankshaft is turned by both banks of cylinders. The angle of displacement is generally between 60 and 90 degrees. Although the most common engines are V-8 and V-6, manufacturers have used V-4 and V-12.

Vulcanize: Process rubber by chemical means, usually in combination with heat, to improve its strength, hardness, elasticity, and to effect bonding to other rubber compounds. Used in the manufacture, repair, and retreading of tires.

V-x engine: !!!.
